Franklin D. Roosevelt began the tradition of building a library at the end of a president’s time in office. There are now 13 presidential libraries in the United States, with Texas home to three of them, the most in any given state.

The Barack Obama Foundation was formed in January 2014 to oversee the development of his presidential library. Chicago seems the most likely location for the library, though Honolulu and New York City are also under consideration.

The University of Chicago, where Obama worked for 12 years as a constitutional law professor, is an obvious contender to house the newest presidential library. Another possible location is Chicago’s Bronzeville neighborhood, an historically black cultural and business center that would compliment Obama’s legacy as the first black president. Obama began his work as a community organizer in the neighborhood of Chicago State University, another contender for the library, while the University of Illinois at Chicago, the state’s largest university, can also make a legitimate bid. The Pullman neighborhood will get a serious look since Obama also worked there as a community organizer in the 1980s. Finally, the former site of the U.S. Steel Corporation offers stunning views of Lake Michigan and could draw hordes of tourists.

The president’s legacy is much greater than just a library. However, because a presidential library can help bolster that legacy, its location is significant. The library will help preserve Obama’s legacy for future generations as well as do the most good it can wherever it winds up being located. But one thing is almost certain: this library will be in Chicago.
